Or, apparently, realistic expectations.

You, do, indeed, deserve public shaming for your complete lack of  
willingness to support IPv6. Your customers have no "realistic choices"  
either. How many other ISPs do they have to choice from? If you cannot be  
bothered to support IPv6, how are they supposed to? ("use a tunnel broker"  
is the *WRONG* answer)

You are an ISP. You don't get to say "NO!" to IPv6. It is what the global  
internet is moving towards. You _WILL_ support it, or you will be left  
behind, and your customers who have little or no other options will suffer  
for it.

This is just *your* flawed perception. Have you bothered to be an engineer  
and figure out _WHY_ it doesn't work? Or do you like keeping your head in  
the sand mumbling "it's not my job"?

If you are providing customer access via 802.11 technology, then yes, you  
do have a serious problem. But it's a problem you already have with v4 as  
well... or do you block _ALL_ broadcast traffic from your 802.11 network?  
Have you checked those networks, because I'm pretty sure there's multicast  
on them already. (windows and mac generate multicast by default)

My experience shows multicast is a problem for 99% of WiFi gear. It's  
handled like all other broadcast and sent at "basic rate" to all stations,  
which is going to be slow as crap. However, IPv6 ND (and RAs) do not  
amount to a volume that will, under normal conditions, kill a WiFi  
network. I run IPv6 over my 802.11a/b/g/n networks; no one has even  
noticed! (even with Truly Ancient Hardware(tm))
